Hmm: I reckon you need to use Formatted Media, which DVD+RW must be. It's Randomly Addressable, so you don't need to Close Session like on a Read-Only Disk. Buffer Underruns are supposed to be irrelevant using DVD+. And the Drive itself can calibrate the Optical Power from the Disk itself. I know I read about this somewhere, and the article in question was saying you could archive tar files this way. Anybody got any further info?
